Engine Cooling - Liquid Cooled Models
Coolant High Temperature Indicator Light
The high temperature indicator light is controlled by a switch in the
engine cooling system on liquid cooled models. If the engine coolant
reaches a certain temperature, the switch completes a circuit that turns
the light on. If you must drive your machine after the high temperature
indicator light has come on, drive slowly and stop frequently to allow
the engine to cool down. See your dealer.
Coolant Level
The coolant level in the coolant bottle must be maintained at the “full
cold” line on the coolant bottle when the engine is cold.
Flushing the Cooling System
To ensure that the coolant maintains its ability to protect the engine,
the system should be completely drained every two years and a fresh
50/50 or 60/40 mixture of antifreeze and distilled water should be
added. This service must be done when the engine is cold. Ask your
Polaris dealer to check the coolant when he performs the fall tune-up
on your snowmobile.
Operating the snowmobile with insufficient coolant will result in
overheating and serious engine damage. Always maintain the
coolant level as recommended.
